摘要：Directed digital signatures are probably the most important and widely used cryptographic primitive enabled by public key technology, and they are building blocks of many modern distributed computer applications. But many existing signatures schemes lie in the intractability of problems closely related to the number theory than group theory. In this paper, we present a new directed digital signature scheme based on general non-commutative division semiring. For this, we construct the polynomials as the elements of additive structure of the semiring and take them as the underlying work structure. Then the signature scheme is developed on the multiplicative structure of the division semiring. And also we present one important application Registration Process in different situations in common practice. For this, we use a directed digital signature, to design a scheme such that the scheme provides a registration number to a person or an organization. The registration number cant be forged and misused and is the strength of the algorithm. The security of the proposed directed signature scheme and registration number is based on the intractability of the Polynomial Symmetrical Decomposition Problem over the given non-commutative division semirings. Keywords: Directed Digital Signature, Polynomial Decomposition problem, Non-commutative Division Semiring, Registration number.
